Switching power supplies from Sunpower with plain metal housing are robust and the elctrical connetor using screw terminals is perfectly applicable also for larger wires cross sections.
Sunpower's switching power supplies have been specially developed for cost-critical applications. The flat metal housings are robust and the electrical connection at the screw terminal is also suitable for large conductor cross-sections. All power semiconductors are thermally coupled to the metal housing. This allows the waste heat to be dissipated to the environment in a defined manner and mounting is possible in all installation positions. The standard devices are available with output voltages from 3.3 - 48 VDC. In addition, there are many types with 1 - 4 output voltages. Ask us about these other models.
